PFMSECCNT<7:0>
Legend: HS = Hardware Set
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-28 Unimplemented: Read as ‘0’
bit 27 PFMDED: Flash Double-bit Error Detected (DED) Status bit
This bit is set in hardware and can only be cleared (i.e., set to ‘0’) in software.
1 = A DED error has occurred
0 = A DED error has not occurred
bit 26 PFMSEC: Flash Single-bit Error Corrected (SEC) Status bit
1 = A SEC error occurred when PFMSECCNT<7:0> was equal to zero
0 = A SEC error has not occurred
bit 25-8 Unimplemented: Read as ‘0’
bit 7-0 PFMSECCNT<7:0>: Flash SEC Count bits
11111111 - 00000000 = SEC count
